/* =============================================================================
   📱 MMS-UI 工具类样式库 - 见名知意版本
   
   🎯 设计理念：
   - 与 WindiCSS 协同工作，避免命名冲突
   - WindiCSS 处理：基础工具类（p-*, m-*, text-*, bg-*等）
   - MMS.scss 处理：业务特定样式（lay-*, sp-*, interact-*, anim-*等）
   
   📐 统一数值体系：4px 递增（1=4px, 2=8px, 3=12px...）
   🎨 统一色彩体系：与 WindiCSS 共享 primary、success、warning、danger
   📱 统一断点体系：mobile(<640px), tablet(640-1023px), desktop(>=1024px)
   
   命名规范：[功能][细节][状态]
   - lay-* : 布局相关（MMS专属）
   - sp-*  : 间距相关（MMS专属，4px递增体系）
   - font-*: 字体相关（语义化命名，与WindiCSS配合）
   - color-*: 颜色相关（MMS专属，业务色彩）
   - text-*: 文本相关（与WindiCSS配合）
   - border-*: 边框相关（MMS专属扩展）
   - bg-*: 背景相关（MMS专属扩展）
   - d-*: 显示相关（MMS专属）
   - interact-*: 交互效果（MMS专属）
   - anim-*: 动画效果（MMS专属）
   - resp-*: 响应式布局（MMS专属）
   - util-*: 工具类（MMS专属）
